SHUTTLE.

T0 all whom it may concern Be it known that' I, VERNON ROYLE, a citiz en of the United States, and resident of Paterson, in the county of Passaie and State of New Jersey, have invented a new and useful Inaprovement in Shuttles, of whieh the following is a specificaition.

My invention relatesto shuttles and more pz'mrticularly to a shuttle f0r nse in a circular 100m, ehe objeet being to provide for' promptly separating the .warp threads in advance of the thread guide and lay t0 such an extent as will permit the weft thread to be pressed into close proximity to the weaving pin or core, and to provide at the same time for leading the thread into the thread guide and lay in a direction appr oximately tangent to the periphery of the weaving pin 01 core, without passing the thread through an eye in the-thread-guide and lay.

Apractical embodiment 0f the invention is repres'ented inthe aecompanying drawings, in which,

Figure 1 is a t0p plan view of a pair of thread guicle and lay holders with thread guides and lays attached thereto in th'e position which they assume when in operation,

the bodies of their respective shuttles not being shown. Fig. 2 is a sectlon in the plane of the line.AA of Fig. 1. Fig. 3 is a transverse section in the plane of the line B-B of Fig. 1. Figs. 4 to 10 inclusive are enlarged diagrammatical sections showing the position ofthe ihreadguide and lay With respect to the weit and warp threads and weaving pin er core;Fig. 4 being tixken in the plane of the warp thread line a; Fig. 5

in the plane of the warp thread line b; Fig. 6 in the plane Of-the warp threadline c;

' Fig. 7 in the plane of. ishe warp thread line d; Fig. 8 in the plane of the warp thread line e; Fig. 9 in the plane 0f the warp thread line f; andliig. 10 in the plane of the warp thread line g.

As the two Wefi: thread guides and lays and their respective holders are similar m 'structure, a description of one will be sufficient for both. The weit thread guide and.

lay is denoted as a wh0le by 1. In its face, teward the weaving pin o1 core 3, whieh' face conforms throughout a portion of its length to the periphery of the weaving pin or. core, there is formed a spiral groove 2, for recei ving and laying the weft thread 4. At the erxd 0f the threz'xd guide and lay,

Where the thread 4 enters the groove 2, tl1e groorre is directed mitwardly away from the weaymg pin or core in a direction approxi mat1ng a line tangent to the periphery of the weav1ng pin er core, as shown at 5. The thread guide and lay l, is attached t0 its holder 6. by means of bolts 7 extencling through from.t he back of the holder 6, and tapped into the back 0f the thread guide and lay 1, as clearly shown in Fig. 1. The

holder 6 is providecl With cliverging arms 8 and 9, by' means of which 113 is 1n ade fast to legs 10 anal 11 011 the body of the shuttle.

The arm 8, to wit: the advance arm 0f the holder 6, is provicled Witl1 a plurality of.

-fences er warp spreaders deneted by 12 and 13, and a fence 01 spreader 14 1s also canied by, the holder G, in proxin1ity to the thread guicle ancl lay l, the said flznce 14 being arranged to coact w ith the fences 12 and 13. These warp spreaclers or fences 12 und 13 are arranged in planes ap'proximately parallel t a plane tangent t0 the weavingpin 01 core 3, and the fence er spreader 14, from its advance endbackto a point about heidway 0f its length, is approximately parallel to the fences 12 and 13. The fences 01' spreaders 12, 13, 14, ha"e their achance ends arranged in substantial alinement, the line of their advance ends being oblique to a radial line diawn 11'0111 tl1e center of tl1e weaving pin 01 core, with the advance end 0f the upper fence 12 on a radial line in advanee of the advance ende of the fences o1 spreaders 13, 14.

The preferred shape of the fences er spreaders 12, 13, 14, is clearly shown in Fig. 2, the advance end of the spreacler 12 being fairly sharp to gradnally separate the warp threads, while the advance end 0f the fence 01 spreader 13 is more blunt to eontiriue the spreading operation, and the advanc e end 01 14 which engages the warp threads m prex imity to the point Wliere the thread g1 11d0 and lay is to press the weft thread 1nto elose contact with the weaving pin or core, has a. blunt end for spreading the warp threads immediately in advance of the action of the thread guide and lay, and is so shaped as to maintain this spread while the thread guide and lay is plaeing the weit thread in positio1i and forcing it by a screvg or cam motio'n firmly against the precedmg weft thread. Furthennore', the positiox'1s of these several fe nces apProximately parallel to a plane tangent t the periphery of the weav* ing pin 01' core end hence oblique to the radial lines Wl1ich the werp threeds.asume, serve to spread the werp threeds to the desired extent during the movement of the shuttle through e short erc, so that there mey be emple tir ne for the return of he werp threeds end e re-crossing of th e seme while in edvence of the on-com'mg shuttle. This provicles egainst any possible feilure in eifectin g e perfect seperetion of the werp threads end it also provides for e greduel but rapid spreading of the threeds totheir meximum opening in proximity to the threed guide end ley, so (hat the letter mey do its work eflectively. The Weit threed 4,

efter pessing over e guide pullej 15, leads inwerdly elong e groove 16 in the threed guide end ley holder end thenoe uninterruptedly into the open end of the groove 2 in the fece of the threed guide end ley.

The Wefli threed is then free to render from the guide pulley 15, to the threed guideand ley, the ebsence of the eye heretotfore commim, freeing th'e threed from eny liability of obstruction due to any smell Dick or m1- evenness in the threed, the direction ofthe threed from the guide pulley 15 to the point where it is finelly pressed into osition in the woven febric departing but little irom astreight line.

The views 4 to 10 inclusive, show Ehe graduel ection of the threed guide end ley end its holder on the weftthreed from the time the fence or spreeder 14 ent ers between the werp threeds up to the time when the weit threed 1S forced into its osition relative 170 weft threeds which heve been previodsly leid. In these views the upper end lower werp threeds ere denoted respectively by 17 end 18.
